This invention relates to a pencil of a'very simple construction which is adapted to hold a marking lead of a verysmall diameter in readiness for use, so as to be projected orwithdrawn into the pencil barrel at will. The marking lead held in writing position can be of a considerable length, owing to the simplicity of the construction of thelead propelling means, thus giving ZLPBIlCll construclead in writing position and a lead magazine for'extra leads,'whereby a considerable amount of writmg lead can be carried in a convenient manner, in the pencil barrel. The

lead holding means is adapted to slidably hold the butt or rear end of the marking lead in writing position in the pencil. It is very desirable, in a pencil of this nature, to have a simple construction and this invention carries out this idea in a practical way.

Figure 6 is a detail ofa' portion ofthe pencil, partially illustrated in cross section.

The pencil A is provided with a barrel 1,

which is formed of thin, hollow tubing with a conicalhollow forwardcnd 2, the apex 3 of whichsis provided with an axial opening 4, whichiis approximately the same diameter or shape as the cross section of a'fine marking lead 5, which'is adapted to be used therein. Themarkmg lead 5 is of a considerablelength and its body portion extends unsupported between its ends through the freely slidable on the end of therod. One f end of the coil spring 9 is secured to the rear portion of the'soc-ket 7 by having thecoils of the springs engage in the recesses or grooves 11 formed in the socket, and the other end of or threads 12 formed in the rod 8. It is-eVi-f dent, however, that the endsof the coil spring- 9 can be soldered or otherwise attached to the collar 7 and the rod 8. This construction of holding means for'the rear end of the marking lead is adapted to hold a lead so that when the sameis ejected from thepenoil and is worn off to such an extent that the forward edge 13. of thecollar .or socket 7 engages the inner surface 14: of the hollowconical end 2 of the pencil barrel 1, the end 10 of the rod 8 will slide forward in the socket 7- and expel all of the marking lead the spring9 has its 'coilsen'gaging in grooves A out of the pencil'as the propelling means of the pencil is operated. 0n the other hand; jthe rod 8 only projects far enough into the v rear end of the socket 7 to pivotally hold" the rear end of'the'marking lead 5,--thus allowing for any lrregularltiesm the barrel construction and giving sufficient. movement from'the pencil barrell', is provided to pro Y ject the marking lead from the'writing end i of the pencil, as required, or to withdraw it 'into the pencil when the propelling mechanism is operated." The propelling mech anism B consists of a threaded member or rod 15' which extends into the rear end of the'pencil barrel 1, and is rigidly secured a by means of its thread and the nut 16 to an operating head 17 The operating head 17, together with the threaded rod 15, are swivellv or rotatably held by the collar closure 18: which is formed with a forward threaded end 19 which is adapted to engage in' the threaded collar 20 which is rigidly heldby I friction, or otherwise, in the enlarged rear portion21 of the barrel 1. When the collar closure '18 is "screwed tight into the threaded sleeve 20 in the pencil A, the threaded rod 15 is held against longitudinal movement therein, but is freely rotatable by engaging and rotating the head. 17 and can be rotated in either direction to operate the threaded rod or'memb'erl5. v

, A threaded nut or member 22 is adapted to be carried by the rod or threaded element 15 and the element or nut 22'is shaped as to frictionally' engage in the channel of passageway 23 formed by the channel. shaped member 24L, whenthe fpropellingmechanism is in A position in the pencil'barrel. Thechannel shaped member 24. is formedof thin material,

and is frictionally or other'rigidly held in the hollow portion of the barrel 1 of the pencil A, being of a suitable shape and provided1w=ith a longitudinally extending rib- 25;, the. edge of which engages against the inner surface of the barrel and causes the longitudinal edges 26 and 27 to also engage the inner surface of the barrel 1, to hold the channel member 24 in'posit'ion in the barrel; It is obvious that the channel member can 35.

' it must frictio'nally engage the inner surbe inserted in any position in the barrel, but

face of the barrel to hold it rigidly in position, or be otherwise rigidly secured therein, where the cross section of the barrel 1 is circu-lar in shape. A slanting flange 28 is rigidly secured to one end of the channel member 24 to form a closure for the forward end of the-chambers 2-9 and 30 formed about the outer surface of thechannel member 24 and by'the barrel casing 1. The chambers 29 and 30 are for the purpose of forming a I magazine for holding extra leads 5, as in- (heated in Figures 1', 2 and 3, in this manner conveniently and simply forming a magazine long length in proportion to the dimensions for the marking leads, which are of akvery of-thepenci-l A. The passageway orchambers 23, formed by the channelrmember 24 a-nd the barrel casing 1, are for the purpose ;o-f receiving the threaded element or rod .15

and the nut 22. The nut 22 frictionally en gagesthe inners'urface of the passagmvay Or -chamber 23, slightly, so as to hold it against free movement therein, and to hold it against rotation but to allow it to move longitudinally therein when in position in the .pencil barrel, as illustrated in Figure 1, and when the operating head 17 is rotated.

' The rear end of the rod 8 is rigidly secured iat 31 to the fnnt22 so that when the nut 22 is moved longitudinally, by rotating the head 17 and the threaded driving member 15, the marking lead 5, held in writing positionin the pencil, will be moved longitudinally in either direction, according to the rotation of the member 15.

The head 17, which is swivelly or rotatably held by the collar 18, has its forward edge expanded so as to form an annular shoulder 32, which engages the forwardend of the threaded end portion of the collar 18 to hold the collar 18 against the shoulder 33 of the vhead 17, thus holding the collar 18 freely rota-table on, but against removal from the forward end of the head 17, Theforward, hollow end of the head 17, which projects and the writing end of the pencil is held upward, causing the rear ends of the marking leads in the magazine chambers 29 and 30 to slide into the recess 34'and thus preventing them from falling out of the pencil on to the floor when the pencil is openedand the ejecting means B is being removed therefrom.

' throughthe zco-llarl8, forms 'arec'ess 34 which will readily receive the ends of the markingleads 5 held in the magazine chambers 29 and 30, if the collar closure l8 -is'unscrewed' I The collar closure 18 forms a 'closure for the magazine chambers 29' and 30. A recess 35 is formed in the rear end of the head 17,

which is adapted to receive an eraser 36, as illustrated 111 Figure 1. ';When the eraser 36 wears down the portion of the same in the recess 35 can be egected either by degrees or entirely from the recess 35 by loosening the nut 16 and operating the threaded rod 15 to forcethe eraser out of the recess.

When the marking lead. held in writing position is entirely used up, and it is desired to put a new marking lead into the socket 7, the head 17 is rotated in a backward direction, causing the nut 22 to travel backward ly on the threaded member orrod 15 to its rearmost position, whereupon the-collar closure The pencil barrel '1 can be formed of a hexagon cross section as illustrated in-Eigures 7 and 8 and a threaded nut member 22 of a similar cross sect-ion so as to properly engage the lnner surface of the hexagon barrel. In this construction, the marking leads 5 are held in suitable sockets 37, "formed in the threaded nut 22 which is adapted -'.to

travel backand forth in the barrel when the projecting mechanism is operated'by the operating head 17. With this hexagon construction or shape of barrel, it is not neces saryto usethe channel membersuch. as 24:,

forthe rear end of the pencil barreland magazine. I l v The construction of this "pencil is extremely simple, but itis obvious that it Wlll effectively hold a marking lead in a practical way, so that it can be projected or withdrawn --into the pencil barrel, asmay be desired.

There are very few parts required'in the construction of thispencil, thus giving an inexpensive device.

The operating head 17 and closure 18 are removable as a unit from the barrel 1 and the magazine portion can also be easily removed, if it is desired, where it is frictionally held in the pencilcasing, this construction allowing the pencil casing 1 to be made up and printed upon, if desired, before the magazine channel member 24 is inserted therein. This is 'important for various uses of the pencil. There are no complicated parts and the removal of the operating parts, collectively, gives a pencil construction'where, if it is desired, owing to the defectiveness, or otherwise, the propelling mechanism can be easily replaced bya new portion or part, and thus give the user of the pencil, a practical device, which is not likely to get out of order, and being a very cheap to manufacture, still giving a pencil of a neat and desirable appearance.

The slanted flange or closure 28, at the forward end of the channel member 24:,prevents any of the particles of lead, which may be broken ofl' from the marking lead in writing position, from being held in the pencil barrel when the propelling mechanism is removed therefrom, but on the other-hand, tends to cause them to be discharged when the pencil is held conical end upward with the propelling mechanism removed therefrom. v

The operating head 17 and the closure 18,

which-are of' any suitable shape, are con-- nected together as aunit and form an exten- Tsion of the rear'end of the pencil barrel,

while the closure collar 18 is positioned adjacent the operating head 17 and is freely rotatable to lock the unit to the barrel or disengage it when desired.- The threaded Prod 15 is attached to theunit and is remov whic I now consider-to represent the best: embodiment thereof, but I desire to have it" understood that the construction shown is only illustrative and that the inventioncan be carried out by other means and applied to uses other than those'above set forth within the scope of thefollowingclaims: 7
